Padded handcuffs and more humiliation

You reach into the bag and pull out a set of well padded handcuffs. "Put your hands behind your back, Skye."

The agitated blonde girl resists at first, but with a little use of your power she spins around and presents her hands behind her back to you. You snap the cuffs on tight, then up her arousal to the same **** as her sister's, but with the same inability to cum. Skye fights desperately to pull her hands out of the cuffs so she can finger herself.

"Oh god!" says Skye. "Fuck! I'm gonna explode if I don't cum soon!"

"Uunnnh!" moans Sunni as she claws at her chastity belt. "You fucker, you can't do this to us!"

You shrug. "Maybe you're right. Okay, I'll do you two a couple favors. First, I'll let you both go as soon as you cum."

"Really?" says Skye.

"Asshole!" spits out Sunni. "That's fine for my sister, but you've still fucked me over since I can't get to my pussy!"

"Well that's where my second favor comes in. From now on, and I mean for the rest of your lives, when one of you has an orgasm, so does the other."

The blonde twins stop struggling for a moment as they think about what this means. Sunni looks down at her chastity belt, then looks at Skye's exposed pussy and restricted hands. Sunni lurches towards her sister, intense sexual need making it hard for her to walk steady.

As Sunni lowers to her knees, you reach inside their minds. They're both bisexual, equally attracted to either sex. You change Sunni to a raging lesbian, completely nauseous at the idea of touching a cock. You send Skye in the other direction, totally hetero. Both girls think they've always been this way and Skye doesn't remember the experimenting she's done with her sister.

Sunni sticks out her tongue and leans towards Skye's crotch, more attracted to her sibling than ever before. Skye lurches backward.

"What the hell are you doing?!"

"Huh?" The look of confusion on Sunni's face is perfection. "What are you talking about, we do this all the time!"

"Ew! No! You're my sister, that's disgusting! Get away from me!"

The two girls start scooting around the shower floor, chasing each other on their knees. The urge to laugh is incredible, you let loose when Sunni slips on a bar of soap and barely catches herself.

"Skye! Stop it! We're never going to get out of this if you don't let me eat you out! Come on, I'm horny as fucking hell!"

Skye curls into a corner, pulling up her knees to protect her tender snatch from her sister. "Well... I am too, but I'm not doing that." The intensity of her sexual need overwhelms her, a shiver runs over her entire body. "Uuunnnhhh! Fuck! This is horrible! I just want to cum!"

"Wellll..." you say dramatically as your clothes disappear. "Perhaps I can give you girls another option."
